Entrails of a Ripe Woman: Scarlet Crevice
"Takao escaped from prison to take revenge on his wife who had informed him of his crimes. Along the way, I met Izumi, a high school girl who had been dating a middle-aged man, and spent the night. Takao appears in front of his wife with a gun in his hand ... The protagonist and the sexually unrestrained school girls, who have revenge but cannot give up their feelings for their wives, dramatically gloss various sexual forms."
